  • VF Control of 3-Phase Induction Motors Using PIC16F7X7 Microcontrollers
    . · The acceleration and deceleration of the motor. can be controlled by controlling the change of the. supply frequency to the motor with respect to. time. 2004 Microchip Technology Inc. DS00889B-page 1. AN889. FIGURE 1: TORQUE-SPEED CHARACTERISTICS OF INDUCTION MOTOR. Breakdown Torque. Torque. Current. Full
  • AC Motors
    A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary (rotor
  • Motor Starters
    Full-voltage starters (manual and magnetic) apply full voltage directly to motor terminals. Two other types, combination and reversing starters, consist of a starter, usually magnetic, with added functions. Some machines or loads may require a gentle start and smooth acceleration up to full speed
  • Appliance motors turn green
    induction motors dominated the fixed-speed appliance era, but are not necessarily the best choice for variable-speed schemes. For example, controllers, for those motors able to manage the high dynamic torque washing machines require, are expensive to create. An alternative motor type
  • The Importance of Effective Motor and Motor Circuit Protection (.pdf)
    . If the. Motors discussed herein are standard characteristic AC. load exceeds the horsepower rating, current will exceed the. induction motors which cover about 80-85% of all motors. FLA and the motor may overheat. The vast majority of motors. used. Motors considered `special purpose motors
  • Copper Shines in Motor Rotors
    Use of rotors cast from copper brings efficiencies that let small motors handle big jobs. * Induction motors employing copper rotors can be smaller than equivalent versions with aluminum rotors. * Copper rotors exhibit lower losses than aluminum which lets them run cooler and be more efficient
  • "Hotrodding" AC Capacitor Motors and Gearmotors ...At your own Risk
    You can get higher starting torque from an AC induction motor by replacing factory specified capacitors with larger ones. But pushing the motor too far beyond design specs is risky. Here's how capacitance affects motor performance.... "Hotrodding" AC Capacitor Motors and Gearmotors ...At your own
